Hello from MrBillDoesMath!
Answer:
I think your formula (2y/x2) is equivalent to
(2*y)/(x^2) where x^2 means x-squared.
If so, then
(2*y)/(x^2) = (2*3)/(4*4) = 6/16 = 3/8
Thank you,
MrB
Pretty good so far its hard also.

Answer:
e) Hence 2, -7 are roots of the equation X² + 5X - 14 = 0
Step-by-step explanation:
given equation : X² + 5X - 14 = 0
⇒ X² + 7X - 2X - 14 = 0
⇒ X·(X + 7) - 2·(X + 7) = 0
⇒ (X + 7)·(X - 2) = 0
⇒ X = -7, X = 2
<u>Hence 2, -7 are roots of the equation X² + 5X - 14 = 0</u>
Answer:
The domain of relation is {1,3,5}
It is not a function.
Step-by-step explanation:
Given the relation {(1, 4), (3, 6), (5, 4), (1, 8)}
We need to find the domain and determine if the given relation is function or not.
The domain of relation is {1,3,5}
But the given relation is not function because we have x=1 twice in the relation and the for the relation to be function the values of domain can't be repeated.
So, It is not a function.
